United States Patent 3,026,704 LOCK MOUNTING MEANS Arthur R. Baker, Bristol, Conn, assignor to The American Hardware Corporation, New Britain, Conn. Filed Aug. 14, 1959, Ser. No. 833,732 12 Claims. (Cl. 70-451) This invention relates to lock mounting means and more particularly to mounting means which are primarily intended for mounting locks on glass doors.

My invention is especially useful in connection with conventional glass doors of the type comprising a single piece of thick glass having metal rails secured to the top and bottom edges thereof, the said rails being formed of extruded aluminum and having longitudinally extending channels therein which open along the top and bottom edges of the door and are adapted to receive the hinges and the lock for the door. The lock may be mounted in the channel at the top of the door or it may be mounted in the downwardly opening channel in the bottom rail so that it may be more conveniently reached for operation, but in installations of the the latter type, it'is preferred to provide for removal of the lock for repair or replacement without removing the door from its hinges.

It is an object of this invention to provide means whereby a door lock may be mounted in or removed from the channel in the bottom rail of a door without removing the door from its installed position.

A further object of this invention is to provide means whereby a door lock may be installed in or removed from said channel through the open end thereof at the free edge of the door.

A still further object of this invention is to provide a mounting bracket for supporting a door lock in said channel which may be installed in or removed from said channel through said open end thereof.

Further objects and advantages of this invention will be more clearly understood from the following description and the accompanying drawing in which:

FIG. 1 is a front elevational View illustrating the bottom portion of a glass door having a door lock mounted therein in accordance with the present invention.

FIG. 2 is an enlarged front view of a portion of said door, partly in central vertical section, further illustrating the lock mounting means of the present invention.

FIG. 3 is an elevational end view of the door of FIG. 2 with the channel cover removed.

FIG. 4 is a sectional front view of a portion of said door illustrating a modification of the present invention.

FIG. 5 is an elevational end view of the door of FIG. 4.

FIG. 6 is a view similar to FIG. 5, but with the channel cover member removed.

FIG. 7 is a view similar to FIG. 4, but showing the opposite side of the door and further illustrating the modified form of the present invention.

FIG. 8 is an isometric View or" the mounting bracket shown in FIGS. 2 and 3.

FIG. 9 is an exploded isometric view showing a portion of the modified bracket and the cover anchoring plate illustrated in FIGS. 4 to 7.

Referring now to the drawing, the numeral 5 denotes the bottom portion of a conventional glass door which is constructed of a single piece of thick glass 6 having a rail '7 secured to the bottom edge thereof. Said rail is formed from an extruded aluminum bar and has a downwardly opening channel 8 therein which extends for the full length of the rail and opens to its opposite ends. The channel 8 is provided to receive a door lock and the lower hinge for the door which, in FIG. 1, is located at the lefthand end of the rail 7.

The present invention is directed to the provision of novel means for mounting a door lock in the channel 8.

, means.

In the form of the invention illustrated in FIGS. 2, 3 and 8, said mounting means include a bracket 9 which is preferably constructed of sheet metal and is formed to provide a U-shaped portion having a bottom wall 10, an inner side wall 11 and an outer side wall 12. The upper ends of said side walls 11 and 12 are bent to form inwardly extending flanges 11a and 12a disposed at right angles to said side walls, and said flanges are provided with notches 13 and 14, respectively, which open to their inner edges. The bottom wall 10 has an opening 15 and a pair of counter-sunk holes 1616 extending therethrough, and the front wall 12 has an access opening 17 in the upper portion thereof.

A door lock of the conventional cylinder operated type is mounted in the channel 8 by my improved mounting Said lock includes a casing 18 having a bolt 19 slideable therein between retracted and projected positions. The said casing is mounted upon the bottom wall 10 of the bracket 9 and is secured thereto by screws 20-2ti which extend through the holes 16-16 and are threaded into said casing. The bolt 19 is aligned with the opening 15 and is adapted to be projected theret-hrough into a keeper 21 in the floor 22 adjacent to the bottom of the door 5 as shown in FIGS. 2 and 3.

The bracket 9 is of substantially the same width as the channel 8 and is adapted to fit therein with the bottom surface of the wall 10 disposed substantially flush with the bottom edge of the rail 7. Said bracket is secured to said rail by means of headed screws 23 and 24 which are threaded into the top of the channel 8 and are adapted to be received in the notches 13 and 14 respectively.

The lock casing 18 has threaded openings, indicated at 25, in its opposite sides, and the opposite side walls of the channel 8 have holes 2626 therein which are normally aligned with the openings 25. A pair of conventional lock cylinders 27-27 extend through said holes 2626'from the opposite sides of the rail 7 and are threaded into the openings 25, said cylinders having flanges 2828 which are disposed against the outer sides of the rail 7. The keyplug in each lock cylinder carries the usual cam 29 and may be operated by a key to move the bolt 19 into and out of locking position with relation to the keeper 21 in the manner well understood by those skilled in the art.

In mounting the door lock on the door, the casing 18 is first secured to the bottom wall 10 of the bracket 9 by means of the screws 29-40. The said bracket, with the door lock thereon, is then inserted endwise into the open end of the channel 8 at the free edge of the doorthis being at the right hand side of FIG. 2so that the notches 13 and 14 are disposed in front of and in register with the screws 23 and 24. The said bracket is then moved inwardly and the flanges 11a and 12a inserted between the heads of the screws 23 and 24 and the top of the channel 8.

When the bracket is in its innermost position and the openings 25 in the lock casing are in alignment with the holes 2626, the screw 2 is tightened with a suitable wrench inserted through the access opening 17 to thereby firmly secure the bracket and lock casing to the rail 7 in the position illustrated in FIG. 2. The screw 23 need not be tightened since this screw is provided with a tapered head and is initially adjusted so that the flange 11a on the bracket will fit tightly between the tapered surface of said head and the top of the channel 8.

When the lock casing 18 has been mounted in its correct position within the channel 8, the lock cylinders 27-27 are inserted through the holes 2626 and threaded into the openings 25 until the flanges 2828 on said cylinders are brought into tight engagement with the outer sides of the rail 7, and the cams 29-29 will then be in position to operate the lock mechanism.

The bracket 9 is preferably made so that the front wall 12 thereof will be located inwardly of the end of the rail 7 so that the open end of the channel 8 may be closed with a cover 30. Said cover is made to fit into the channel 8 and is disposed against the outer side of said wall 12, and the outer surface of said cover is preferably flush with the free end of said rail. The cover 36 is secured in position by means of horizontally spaced screws 31-61 which extend therethrough and are threaded into holes 3232 in the wall 12.

The channel cover 30 above described is especially made for use with the bracket 9 shown in FIGS. 2, 3 and 8, but in order to permit the use of existing channel covers intended for prior types of mounting devices and having vertically instead of horizontally spaced screw holes, I have devised the modified form of the present invention shown in FIGS. 4 to 7 and 9. In said modified form, the conventional channel cover 30a is secured against the outer side of the front wall 12 of the bracket 9 by means of screws 33-33 which are threaded into vertically spaced holes 34-34 in a T-shaped anchoring plate 35 that is slidably disposed against the inner side of said wall 12 and has a stem 36 which projects through a notch 37 formed in the bracket to permit lowering of said plate and to provide access to the lower screw hole 34.

In mounting a lock with the modified form of mounting bracket, the anchoring plate 35 is lowered to the position shown in FIG. 7 to permit access to the head of the screw 24 through the opening 17. After said screw has been tightened, the anchoring plate is raised to the position shown in FIGS. 4 and 6 and the cover 30:: is placed over the end of the bracket and secured in position by inserting the screws 33-33 into the holes 3434 in said anchoring plate and tightening them,

It will be understood from the above description, that,

my invention provides improved mounting means for locks which is adapted for mounting a lock in the channel 8 by inserting the lock into the said channel from the outer end thereof to thereby eliminate the necessity of removing the door from its normal position.
